abstract background: correction of severe kyphosis is a challenging operation in spinal surgery. a two stage operation has been commonly used: anterior release and decompression followed by posterior correction and fusion. we describe the posterior vertebral osteotomy technique for correction of severe and rigid kyphosis through posterior-only approach. methods: twelve patients (six male and si...

Submit Manuscript | http://medcraveonline.com rare causes of bone marrow signal alteration in vertebral column. Other causes of bone marrow signal alteration in vertebral column includes variants of normal, marrow reconversion, tumour (myeloproliferative disorders, metastatic, or primary), radiation, fracture, degenerative change, infection, inflammatory arthritis, and osteonecrosis [2]. We des...

Most anuran larvae show large lateral oscillations at both the tip of the tail and the snout while swimming in a straight line. Although the lateral deflections at the snout have long been considered an inefficient aspect of tadpole locomotion, a recent hydrodynamic model suggests that they may in fact help generate thrust. It is not clear though exactly where this bending takes place. The vert...

Actinomvcosis seldom involves the vertebral column. Only four out of 670 patients with actinomycosis reviewed by Sanford and Voelker (1925) had rib or vertebral involvement. It is clear that in the past the diagnosis has been difficult and that tile condition has often been mistaken for Potts disease. Among the reports of sixty cases of mycosis of the vertebral column Meyer and Gall (1935) foun...

The vertebral column has evolved to accommodate the broad range of locomotor pressures found across vertebrate lineages. Xenarthran (armadillos, sloths and anteaters) vertebral columns are characterized by xenarthrous articulations, novel intervertebral articulations located in the posterior trunk that are hypothesized to stiffen the vertebral column to facilitate digging. To determine the degr...

Aim. To summarize recent studies on morphological deviations of the cervical vertebral column and associations with craniofacial morphology and head posture in nonsyndromic patients and in patients with obstructive sleep apnoea (OSA). Design. In these recent studies, visual assessment of the cervical vertebral column and cephalometric analysis of the craniofacial skeleton were performed on prof...
